BPP Renewables has extensive experience in the design, analysis and testing of cables, umbilicals and their components. Tests are performed in BPP Renewables’ laboratory supported by an extensive network of testing facilities.

Tests include both mechanical and electrical performance verification, thermal analysis, environmental stress cracking (ESC), chemical analysis tests and forensic examination. testing is carried out to internationally accepted standards including those from the American National Standards Institute (ANSI), American Petroleum Institute (API), American Society for Testing and Materials (ASTM), Insulated Cable engineers association (ICEA), International electrotechnical Commission (IEC), International Organization for standardization (ISO), National electrical Manufacturers association (NEMA), and National association of Corrosion engineers (NACE).

Tests include:

  • Tensile (or combined torsion balance and tension)
  • Fatigue loads
  • Hydrostatic loads
  • Combined tension and bending (or reeling)
  • Hardness
  • Impact
  • Electrical
  • Conductor resistance
  • Screen resistivity
  • Insulation resistance
  • High-voltage direct current (DC)
  • High-voltage alternative current (AC)
  • Complete voltage breakdown
  • Partial discharge (PD)
  • Loss angle (tanδ or dissipation factor)
  • Capacitance
  • Inductance
  • Heating cycle voltage
  • Current rating (or ampacity)
  • Thermal Analysis
  • Differential scanning calorimetry (DSC)
  • Thermo-gravimetric analysis (TGA)
  • Ageing
  • Environmental Stress Cracking (ESC)
  • Hydrogen embrittlement (HE) test + hydrogen analysis
  • Sulphide stress cracking (SCC) and stress corrosion cracking (SCC)
  • Examination and Chemical Analysis
